It didn't exactly sound convincingly viable though, imo. Edit: Coincidentally, there's something new that came up in a recent report in Science: http://www.sciencemag.org/cgi/content/abstract/324/5923/74
Dont you love it when people quote and miss stuff out, if your going to modify a persons post make sure you get it right
